Under the Information Technology Act, 2000, a person who knowingly conceals or alters computer source code used for a computer network, when required to be kept by law, commits an offence. An investigator tracing an online fraud uses the IP address logged by a website. Which statement about the technology fundamentals involved is correct?

A logged IP address identifies the network connection used, not necessarily the person. Because addresses are often dynamic or shared, investigators need the internet service provider's records to link the address to a subscriber, and further evidence to attribute the act to an individual.

  1. AAn IP address alone always identifies the individual who committed the act, so no further investigation is needed
  2. BA logged IP address identifies the network connection used; the internet service provider's records are needed to link it to a subscriberCorrect
  3. CAn IP address is permanent for each device worldwide and never changes
  4. DAn IP address is the same as an email address and reveals the sender's name

Explanation

An IP address points to a network connection, often dynamically assigned or shared via NAT. Investigators must obtain ISP logs to tie it to a subscriber, and further evidence to tie it to a person. Claims that it always identifies an individual or is permanent ignore dynamic allocation.
